Sarus cranes: the tallest flying birds



 


Sarus cranes are seriously tall birds towering about 5.9feet, but rather than intimidating presence they are self effacing to the point of shy. If you are travelling in north India by train, in particular the rice belt of UP (it also is the State bird of UP), keep an eye out for Sarus cranes, you are very likely to see a pair or atleast hear the characteristic trumpet calls. Sarus is India’s only resident breeding crane specie and prefers marshy wetlands, the name Sarus comes from Sanskrit ‘Sarhans’ meaning birds of lake. These are Vulnerable species and are found in patches of central India and limited regions in East Asia and strips of northern Australia. Sarus crane (Grus antigone) was once a well known sight in India, though in recent times it has declined rapidly. A survey in 1980s pegged the numbers at 12,000 while by late 1990s it had reduced to as low as 2000. I am not privy to latest figures, it must be precariously low. Less than 2000 is not Vulnerable, it is Critically Endangered, I guess IUCN needs to update on this one. The main cause of decline seems to be wetland destruction, these birds are generally found where industrial and urban sprawl has not taken place, and where agricultural practices are still traditional. The shift to cultivation of sugarcane, indiscriminate use of pesticide and criss-crossing power cables seem to be having a detrimental effect. Cranes are indicator species, indicating the health of wetlands and ecosystem. 


The zoological name Grus antigone is quite interesting. In Greek mythology Antigone is the daughter of Oedipus, she defied masculine authority, though she ended up killing herself. Fidelity is one factor that has seen to it that this bird is treated with care since time immemorial by Indians, not to forget it was the pain of the Sarus crane that inspired Valmiki to write Ramayan. British crusaders though had different take on affairs of the world (they still do, with ‘sexed up’ versions!!) and went on shooting spree, even keeping records as matter of pride. There is a novel by Khushwant Singh I Shall Not Hear the Nightingale wherein the central character is instigated to kill the Sarus crane “…if you are going to funk shooting birds, you will not do much when it comes to shooting Englishmen. You will say ‘why kill this poor chap, his widow and children will weep’ or ‘his mother will be sad’…this is what is meant by baptism by blood; get used to the idea of shedding it. Steel your heart against sentiments of kindness and pity. They have been undoing of our nation. We are too soft.”  


Jehangir the Mughal king was an avid observer of avian specie so much so many have pointed out that he would have done remarkably well, and happier man, as the head of BNHS or curator of a natural history museum. He had a keen temperament of a scientist, he tried personal observations and experimental approaches to understand natural phenomenon. Here his observation of nesting Sarus cranes “…a strange thing is that on the other days the pair of Saras cranes took five or six turns sitting on their eggs, but during this twenty four hour period while it was raining and cold, the male sat on the eggs to keep them warm continuously from dawn until midday. From the midday until the morning of the next day the female sat continuously –lest the eggs are damaged or spoiled by the cold while they were getting up and sitting down. In short, what a human being comprehends by the guidance of his reason animals do by an instinct made innate in them by eternal wisdom. Even stranger is the fact that at the beginning they kept the eggs next to each other under their breasts, but after fourteen or fifteen days had passed they made enough space between the eggs so there wouldn’t be too much heat and eggs wouldn’t be spoiled…”    (from The Jahangirnama

Stopping by the Woods


I was reading Stopping by the Woods on a Sunday Morning, it was one of the earliest articles written (1930) by Salim Ali where he exhibits skills required in tracking bird nest. He meticulously locates nests of Purple-rumped Sunbird, Yellow-eyed Babbler, Tailorbird, Fantail Flycatcher, Common Iora and Baya in the outskirts of Mumbai. Notes Salim Ali “…the trick of locating nests, therefore lies not so much in traversing miles of likely country as in keeping an ever-watchful eye as you slowly saunter along, and patiently waiting for the birds to give away their secrets of their own accord”. He also writes “we shall select some Sunday morning late in August for a jaunt into the exquisite country surrounding the city. The heaviest blast monsoon is blown over, and we may now look forward without undue optimism to fine weather. The air is delightfully cool, the sky thinly overcast; banks of threatening nimbus drift across the heavens resulting only in occasional drizzles which help to subdue the uncomfortable steamy vapour that begins to rise immediately after the sun peeps out of his cloudy veil”…. “A monsoon ramble through the woods will delight anyone who has the eyes to see and the soul to wonder at the romance and charm of this other world within our world. The electrification of the suburban railways has thrown the delightful country in the environs of Bombay within the comfortable and speedy reach of everybody. To the lover of the out-of-doors, the opportunities are such as might rightly be the envy of the less fortunate dwellers of almost every one of the other large cities in the country. Yet, how few are there who will sacrifice their Sunday morning sleep.”  


Reading this piece ofcourse reminded me of Robert Frost, the title is undoubtedly influenced by one of his famous poems Stopping by the Woods on a Snowy Evening. The last few lines you could find at the table side of Nehru at Teenmurthi Bhavan indeed that is how I first heard about this poem.
  

Stopping by Woods on a Snowy Evening


Whose woods these are I think I know.
His house is in the village, though;
He will not see me stopping here
To watch his woods fill up with snow.

My little horse must think it queer
To stop without a farmhouse near
Between the woods and frozen lake
The darkest evening of the year.

He gives his harness bells a shake
To ask if there is some mistake.
The only other sounds the sweep
Of easy wind and downy flake.

The woods are lovely, dark, and deep,
But I have promises to keep,
And miles to go before I sleep,

And miles to go before I sleep.
